cmake: add_llext_target: use toolchain-specific partial linking option

Browse source 
The partial linking option depends on the linker used in the build
process, and this flag is already defined by the Zephyr toolchains.
Use the $<TARGET_PROPERTY:linker,partial_linking> generator expression
to retrieve it instead of hardcoding the value for the GNU linker.
